Tool holder provided with a damping means
First Claim
1. Tool holder provided with a damping means (2) in the form of an elongated body having a substantially cylindrical surface, which is arranged in an end compartment (3) of the tool holder (1) having a substantially cylindrical surface corresponding to the substantially cylindrical surface of the elongated body, and closed at its end by a body (4) for receiving a rotative tool like a reaming head or by a milling element, wherein the substantially cylindrical surface of the elongated body and the substantially cylindrical surface of the end compartment of the tool holder define a substantially uniform envelope therebetween, characterized in that the damping means (2) includes at least one elastically deformable means (5), at least close to each end of the cylindrical surface of the elongated body, where said elastically deformable means (5) extend between the envelope of the substantially cylindrical surface of the elongated body of the damping means (2) and the substantially cylindrical surface of the end compartment (3) of the tool holder (1), and are clamped between the wall of the compartment (3) and the damping means (2) to carry out the absorption of radial vibration movements provided by the held rotative tool and transmitted to the compartment (3) of the tool holder (1), and where the ends of the damping means in operable position are spaced apart from the end of the end compartment, such that shocks provided by slight axial movements of the damping means (2) itself in the compartment (3) are absorbed by the at least one elastically deformable means substantially without axial compression.

Abstract
The present invention relates to a tool holder, such as a reaming head (1), or a milling arbor, provided with a damping means (2) in the form of an elongated body, which is arranged in an end compartment (3) of the tool holder (1), which compartment is of appropriate shape and size, and closed at its end by a body (4) for receiving a reaming head or by a milling element.
Tool holder characterized in that the damping means (2) is of the type presenting only radial absorption, and it is provided with at least one elastically deformable means (5), at least close to each end, where said elastically deformable means (5) extend between the envelope of the damping means (2) and the wall of the compartment (3) of the tool holder (1), and are clamped between the wall of the compartment (3) and the damping means (2), and where the ends of the damping means extend in the compartment (3) without stress.
The invention is applicable more particularly in the field of accessories for machine tools, with digital control, machining centers, flexible cells and workshops.
